Answer:
520<400+15x
15x>120
15x+400>520
Explanation:
Pay of Dan's car wash attendant job =$400 per week
The amount he earns per hour walking dogs = $15
Let the number of hours spent walking dogs in a week = x
Therefore, total earning for walking dogs =$15x
Since he wants to earn more than $520, we have that:
We can rewrite this as:
If we collect like terms, we have:
So the inequalities are:
0. 520<400+15x
,
1. 15x>120
,
2. 15x+400>520

Add all her purchases together
97.62 + 22.95 + 14.78 = 135.35
The total tax is 6.5% sales tax, and 0.5% country tax
6.5% + 0.5% = 7%
Multiply the total amount spent by the total tax
Remembering that you need to convert the 7% into an integer, by simply diving by 100 first
135.35 * 0.07 = 9.47
